' ELECTRICAL FIXTURE.

Specification of Letters Patent.

' Patented May 6, 1919.

Application filed October 15, 1917. Serial No. 196,699.

To all whom it may concern:

p a full, clear,

Be it known that I, WILLARD J. ALLPHIN; a citizen of the United States, residin at Portland, in the county of Multnomah'and State of Oregon, have invented certain new and useful Improvements in Electrical Fix tures; and I do declarev the following to be and exact description of the invention, such as will enable others skilled in. the art to which it appertains to make and use the same. 4

This invention relates generally to electrical fixtures, and more particularly to certain new and useful improvements in de vices forconnecting wires together.

The principal ob] ect of the invention is to provide a fixture by which a pair of conductors'may .be tapped or connected to a pair of circuit .wires so that a head can be taken from the same. v I) 'Another object of the invention is to provide a device of this character which will be extremely simple, strong, durable and inexpensive in construction, eflicient and reliableln operation and well adapted to pose for which it is designed.

Withthese'and other objects in view, the invention consists of certain novel features ofjconstruction, and the combination and arrangement ofvparts as will be hereinafter fully described and claimed. In the accompanying drawing,in which similar reference characters designate like parts throughout the several views; I Figurel is a front elevation of a device constructed in accordance withthis'invention.

Fig. 2 is a similar view of the device, the block which fits into the body member of the same being removed.

Fig. 3 is a longitudinal sectional view, of the devicetaken substantially on the line 33 of Fig. 5.

' Fig. 4 is a longitudinal sectional view of the device-taken on a plane at right angles to the plane on which Fig. 3 is taken, the block which forms a part of the device being shown detached from the same.

Fig. device. A

Fig. 6. is a view similar to Fig. 3 showing the pur- 5 is a transverse sectional view of thethe manner in which a device is connected to a number of electrical conductors.

Fig. 7 is a longitudinal sectional view taken on the line 7 7 of Fig. 6 and Fig. 8 is a transverse sectional view taken 4 on the line 88 of Fig. 6.

Referring-more particularly to the drawings, the numeral 1- designates a cylindrical casing or body member which is hollow, it being recessed from the front thereof as at 2. Extending through the ends and one side of the body member 1 are openings 3 and *1 respectively, the openings or apertures 3 being-arranged centrally in the ends of the member while the opening 4 is disposed in said side midway of said ends.

The recess or main cavity 2 is preferably rectangular in configuration, and a rib 5.is formed on its bottom surface, this rib dividing said bottom surface into. substantially flat portions 6. The rib 5 extends longitudinally of the body member 1 vided with an enlarged portion 7 midway of its ends, and this enlarged portion 7 is provided with an internally threaded opening to receive the threaded, end of a screw and is proor fastening member 8 by which a block 9 is maintained in the recess 2. This screw forces the block 9 and body 1 to clamp the insulation or covering of each pair of wire terminals.

This block 9'isprovided with a central openinglO through which the screw 8 extends; notches 11 at its upper and lower ends, ,disposed adjacent the openings 8; and notches 12 at its sides.

Mounted upon the two flat portions 6 of the recess 2 in any suitable manner is-a pairof bars 13 and 14, said bars being each provided with atrio of binding screws 15. The

- bars 13 and 14 and alsothe binding screws 15 are made of conducting material while the body member 1 and block 9 are made of non-conducting material.

The device while being generally useful as a connector for electrical conductors, is especially useful for tapping a lead into a pair of conductors. In this case, the pair of conductors is cut and one end of the pair is inserted through the opening 3 in one of the ends of the body member 1 and conncted to the adjacent binding screws 15. -The other end of the pair of conductors is extended through the opening 3 in the other end of the member 1 and connected to the adjacent binding screws 15. The leadwires are inserted through the opening 4 of the side of the body member 1 and connected to the middle body screws 15, the terminal which crosses the rib 7 passing through a notch 7 in the rib. The block 9 is then placed in the recess 2 and forced against the wires or against the insulation thereof.

' Owing to the fact that the notches 11 and 12 are curved the wires will be bent, and this bending aids the binding or clamping of the wire covering :in firmly anchoring them to j the device. v

The block 9 is provided with a notch 12 in each side thereof merely for the purpose of making it symmetrical and reversible, it being obvious that only one notch .comes into play When the block is inserted in the recess and the body member.

From the foregoing description, taken in connection with the accompanying drawings, the construction and use of the device will be readily understood without a "more extended explanation.

As various changes 1n form, proportion, and in the minor details of constructlon may be resorted to without departing from' the spirit of this invention, it is to be un- F derstood that I do not wish to be limited to ing ri'b, another side of said body having a wire-receiving aperture which communicates with said main cavity substantially opposite the middleof said rib, 'apair of conducting bars secured to said bottom on oppositesides of said rib, each of said conducting bars having-a binding screw at each end and a binding screw' at its middle, an insulating block fitted closely and adjustably in said main cavity and normally having its inner end in position to partly close the wire-receiving apertures, and a fasten-' ing extending through said insulating block into said riband being operable to adjust said insulating block in said main cavity to effect the bending and binding of the pairs of wire terminals where they enter said main cavity when they extend through said apertures, whereby said pairs of wire terminals and their binding screws are convenient to one another and can be easily and advantageously connected in an insulated relation to one another.

2. An electric wire coupling comprising an insulating body formed with a main cavity which opens through only one side of the body and has its bottom between the opposite side and middle of the body, said bottom having thereon a transversely notched insulating rib, two opposite sides ofsaid body being formed with wire-receiving apertures which communicate with saidmain cavity substantiallv at the respective ends of the insulating rib, another side of said body having a wire-receiving aperture which communicates with said main cavity substantially opposite the notch in said rib, a pair of conducting bars secured to said bottom on opposite sides of said rib, each of said conducting barshaving a binding screw at each end and a binding screw at its middle, an insulating block fitted closely and adjustably in said main cavity and being formed with notches that substantially register with said wire-receiving apertures respectively and a; fastening extending through said insulating block into said rib and being operable to cause said insulating block and insulating body to bend and bind the pairs of wire terminals where they enter said main cavity when they extend through said apertures and notches, whereby said pairs of wire terminals and their respective binding screws are convenient relative to one another and can be easily and advantageously connected and whereby one of the terminals of a pair is permitted to cross said rib without obstruction or inconvenience in attaching it to one of the binding screws of the middle pair, because the notch in said rib provides a passage for this one of the terminals.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
